Hi everyone, I just recently received a brand-new Russian 8R clone which I was looking forward to getting started I am not new to this type of stove so I was able to start it without any problems. However, it does not roar, it barely produces some heat output. Any ideas what might be causing this? I am using white gas. I thought being brand-new it needed ample time to warm up especially in cold temperatures like forty degrees. Any suggestions on how to fix it? I have used the cleaning needle but no difference.
